Im in the processes of final touches of Home Entertainment Center setup in my living room and asking for advice from the AVS experts for a subwoofer that would complement the equipment I have already purchased. I was originally going to mount the 65" TV on a 15' 4" wall but fell in love with a beautiful yet massive 10' Fairmont Empire burled wood cabinet with piers, lights and an overhead bridge with lots of storage for DVDs etc. The console has a drawer rather than a separate hidden shelf for the center channel so the center channel will be set just above the TV on a shelf directly under the bridge connecting the tiers and tilted down toward the main viewing area (a couch).
The equipment I have is this so far and I am looking for a recommendation for a wireless subwoofer that complements what I have as well as the room size (15' wide and 18' long), with 9' ceilings, wood laminate floors and (facing the TV) on the right hand wall are two 48"w x70"h windows with wood blinds separated by a, 7' wide fireplace. Behind the couch in the 15 x18 TV room the room adjoins another open small dining room area that is 12 x 12 essentially making the entire are 15 x 30. The couch is parallel to the TV wall and is approximately 14 feet from the TV.
Panasonic 65" TC-PC65ZT60 Plasma TV
Martin Logan Motion 40 floor speakers (2) with Audioquest Type 4 speaker wires
Martin Logan Motion 30 Center Channel with Audioquest Type 4 speaker wires
Pioneer Elite VSX-70 7.2 630 watts) A/V home theater receiver
Audioquest Cinnamon HDMI cables
Panafax M4300-PM with 9 outlets and 2 coaxial RF connections
The TV room is downstairs below an upstairs master bedroom and because the joists in the ceiling run parallel to the TV wall it would make mounting side speakers in the walls to the right and left of the couch and rear speakers behind the couch in a portion of the ceiling 5' directly behind the couch that drops down a foot that conceals ductwork that surrounds the adjoin dining room a sheetrock ripping-up mess. Had the joists been perpendicular to the TV wall the speaker wires cables could have been more easily run through the ceiling without having to drill a hole in each joists to run the wires through.
So for now I will just go with two floor speakers, a center channel and add a subwoofer. At some point within the next six months I may decide to try to add at least the 2 side speakers (maybe pull the crown molding along the ceiling/side walls off and run wires behind that instead) and maybe even add rear speakers. Hence, the reason for buying a 7.2 rather than a 3.1 or 5.1 Pioneer Elite A/V. Because the couch facing the TV wraps around to the left and also runs along most of the left wall there is not enough room on the left side of the 10' TV credenza to place a second subwoofer so I will place the two Martin Logan Motion 40s floor speakers about 6"- 1 foot from each side of the piers of TV Entertainment Center.
So I would place whatever subwoofer I go with on the floor to the right of the TV cabinet near the edge of the fireplace (rarely used) about 4" right of one of the windows (bottom of window ledge is 12" off wood laminate floor) perhaps on an Auralex SubDude 15" x 15" x 3" Isolation Riser I read about since there is a separate wall power outlet right below the window.
The cabinet in picture below is currently about 18"-20" off wall awaiting delivery of Panafax Power Condition/Surge protector as well as a Panasonic rep who is coming out in 3 days to fix the fan noise from Panasonic Plasma TV. The red chest on the floor is where I am thinking of setting the sub. Its about 40" from the right Martin Logan speaker which I am directing at an angle back toward the center of the couch.. Is that too close? When in Best Buy I notice that whenever testing speaker when he turned the sub on for movie viewing I would turn my head to the right looking to see where the rumbling noise was originating from. I realize that two subs out in front of the console would be ideals but the room is already crowded and I would prefer not to do that.
So yes this is long winded but I would greatly appreciate advice regarding SUB as well as any future side or rear speaker in terms of choice and appropriate woofer diameter and wattage complementary with exiting MartinLogans if that is important. Thanks for the read and any advice greatly appreciated including placement of speakers and subwoofer(s) relative to each other.
